Digital Radio: Dab/Dab - Blaupunkt 400 Serie Mode D'emploi

8. Digital radio: DAB/ DAB+
Digital Audio Broadcasting (DAB for short) is the digital
successor to analogue FM broadcasting. Digital transmission
has some differences from the familiar analogue FM radio:
Several stations are broadcast on one channel – the so-called
ENSEMBLES (= programme packages).
The stations in an ENSEMBLE are called SERVICES (= stations
and/or data services).
In Germany, for example, the ENSEMBLES are available
regionally from public broadcasters; moreover, there are
currently two ENSEMBLES that can be received throughout
Germany: DR DEUTSCHLAND and ANTENNE DE.
The stations do not output disagreeable noises known from
FM; a station is either heard with a consistent quality or not
heard at all when error correction is no longer able to
reconstruct the signal, accompanied by short, so-called
"bubbling" noises.
Starting to play the DAB/DAB+ radio
Use the SRC button to select one of the memory levels DAB1
dAB2 or DAB3.
Note: Some memory levels are inactive depending on the
setting; for example, only the DAB1 memory level is active.
See "SETTINGS".
Note: There are 5 memory slots available for each memory
level.
Searching/scrolling through stations
By turning the right button/knob, you can scroll up (clockwise)
or down (counter clockwise) through the stations in the
current Ensemble.
When turning, a new station is displayed; when you stop
turning, the displayed station is recalled and played.
After passing the first or last station of the current Ensemble,
the display will show <<< or >>>. You can now turn the knob
in the opposite direction to stay in the current Ensemble or
wait a moment while the unit automatically searches for and
plays the previous (<<<) or next (>>>) Ensemble.
Note: This function is the default setting for the right
button/knob in the DAB mode, but it can be changed, see
"SETTINGS".
If the basic setting has been changed, first select the function
by pressing the right button/knob; the SERVICE indication will
appear.
Ensemble Search
Press the right button/knob once, the display briefly shows
ENSEMBLE.
Then, turn the right button/knob in the desired direction to
find Ensembles on the lower or higher channels. The display
shows the current channel as you search until you find a new
Ensemble.
This search works the same way as the search that starts when
scrolling through stations when <<</ >>> is displayed – see
the previous section.
Searching the Preset List (Browse mode)
Press the right button/knob repeatedly until BROWSE appears
in the display.
Then, turn the right button/knob to scroll through the list of
stations stored in the unit.
Once the desired station is found, select it by pressing the
right button/knob.
Note: You can use the menu (see "SETTINGS") to start DAB
SERVICE SCAN, which updates the station list and removes
inactive stations from it.
Note: You can set the browse mode as the default setting
for the right button/knob in the DAB mode – see "SETTINGS".
PTY Search
If the PTY (programme type) function is enabled (see
"SETTINGS"), the PTY function can also be selected by pressing
the right button/knob.
Turn the right button/knob to start searching for the preset
PTY code (see "SETTINGS" for the pre-selection of PTY type).
Storing/selecting saved stations
You can save your favourite stations in the station memory
using the 1-5 buttons. Each memory level can store up to 5
stations.
Set the desired station as described above.
Then, press the desired memory button for about one second
until a beep confirms that the station has been stored; release
the button after the beep.
You can recall a saved station by briefly pressing the memory
button.
Playing saved stations (P-SCAN)
You can play back all stations at the selected memory level:
To do this, press the MENU button for more than one second.
The display will show P-SCAN and the current SERVICE.
The P-SCAN function continues until terminated by pressing
the right button/knob.
Playing the available stations (SCAN)
You can play all stations in the selected frequency band:
To do this, press the right button/knob for more than one
second.
The device first updates the service list with a scan, and then
displays SCAN and the current SERVICE.
The scanning (SCAN) continues until stopped by pressing the
right button/knob.
